Abstract: The invention relates to a method and a device for the detection of magnetic particles (1) in a sample chamber (112). After introduction of the sample into said sample chamber (112), the magnetic particles (1) are first retained within the sample chamber (112) and kept away from the sensing surface (111) by an appropriate magnetic field (B) to allow for an incubation of the sample with reagents. A reference measurement may be made during this incubation period (TI), preferably at the end thereof. After incubation, the magnetic particles (1) are allowed to contact the sensing surface (111) where a target measurement can be conducted.

Abstract: The present invention relates to a method for evaluating the start of an assay in a fluidic chamber, wherein said start of the assay is based on the dissolving of a reagent in a region of interest in said fluidic chamber. The method may be based on the detection of an optical effect in the region of interest caused by the dissolving of the reagent, comprising the steps: obtaining an optical signal from one or more sub-sections of said region of interest; processing said optical signal to a Boolean signal; and defining the start of the assay based on said Boolean signal. The present invention also relates to a method for evaluating the start of an assay comprising an electrical detection of a change in the conductivity or permittivity of fluid due to the dissolving of reagent as mentioned above.

Abstract: A system for providing sensory feedback includes a garment (106) that is configured to flexibly and snuggly fit over a portion of a subject. The garment includes one or more sensors (104) disposed therein to monitor activity of the subject or monitor points of interest of the subject. An interpretation module (115) is coupled with the sensors to receive sensor signals and interpret the sensor signals to determine if conditions are met to provide feedback signals to the garment. A feedback modality (108) is incorporated into the garment and is responsive to the feedback signals such that the feedback modality emits energy from the garment to provide sensory information to assist a physician during a procedure.
